摘　　要： 在云南个旧矿区卡房矿田地质特征研究的基础上,分析了该矿田的遥感线性构造特征、环形(弧形)构造特征及线环构造组合特征,通过等值线法显示和计算遥感综合信息量,由遥感综合信息量频数曲线图的拐点确定了找矿信息临界值为7.5和15,划分了一、二两级找矿远景单元,类比已知成矿区,最后提出了五个成矿预测区。 On the basis of the geological features of the Kafang ore field, Gejiu mining district in Yunnan Province, by analyzing the features of linearity and ring structures and the combination of linearity and ring structures in the Kafang ore field, we present the synthetic remote-sensing information by isolines, and then calculated the critical ore-hunting values to be 7.5 and 15 by the inflexions of the frequency curve for synthetic remote-sensing information. Finally, by comparing with the values of a known area, all the perspective units are divided into two grades and five perspective districts of mineralization are put forward.
